sorry if this question is somewhat amateur however could somebody please check my wiring intentions regarding BMV-712 Smart?
I have two 12 V | C20 | 200 Ah lead acid batteries connected in parallel via a busbar (cables of equal length to balance resistance).
If I've understood correctly, the shunt 'Battery -In' should connect to the negative busbar whilst B1 should connect to the positive busbar.
The battery capacity should be set to 400 Ah in the App.
If my understanding is correct B2 (Aux) can't be used to measure the Midpoint as my battery bank is 12 V; could however the temperature probe could be used to measure the batteries via the positive busbar?
Below is a sketch of my intended set-up.
